ORNAMENTAL CHAIN.

Application led August 4, 1925.

To all @0710mt may concern.'

Be it. known that I, GEORGE KoLLs'rnDn, a citizen o1c the United States,residing at Frovidence, in the county of Providence and State oi' RhodeIsland, have invented certain new and useful Improvement-s in OrnamentalChains, of which the following is a specification. v

My invention relates to ornamental chains such asv eXpansib-lebracelets, linkages, bands, girdles, and garte-rs, of the hollow unittype.

The essential objects of my invention are to ena-ble thebodilydetachment-oitl any link or unit from a chain ot' the above type withoutthe necessity of moving or twisting the link to be removed into anangular position relatively to the remainder of the chain, and to attainthese ends in a strong, simple, and inexpensive structure.

My invention consists in the construction, means. Vand mechanism forproducing the results above specified substantially as hereinafterclaimed.

In the accompanying drawings which form a part of this specification,and wherein like reference characters indicate like' parts throughoutthe views,

Figure 1 is a. fragmentary rear elevation of av chain or braceletembodying my invention,

Figure 2, a section of the same on line 2 2 of Figure 1,

Figure 3, an enlarged section on line 3 3 of Figure 2, Y

Figure 4, a section on line 4 4 of Figure 1, and

Figure 5, an enlarged perspective view of one of the connecting units.

My chain as .herein illustrated includes outer tubular or hollow linkmembers or units, and enclosed connecting link members or units,indicatedin a general way by 10 and 11 respectively. Each unit 10comprises a transversely curved front plate 12 with its lateral edgesrolled over upon a transversely curved back plate 13 to form marginalbeads 14. Integral with the ends of the plate 12 are inwardly bentflanges forming the end walls 15 provided with centrally cut awayportions forming openings 16. The ends of each back plate 13 areinwardly turned at right angles to form the Serial No. 48,046.

walls 17 provided with peripheral cut away portion or of less heightthan the wallsl 15, thus formingresultant arcuate openings 18registering with the openings 16.

Fach connecting unit 11 comprises an oblong transversely curved plate orbody 19 provided with lateral guide shoulders 20. One end of thel plateis bent at right angles to form a liange 22. Near its other end there iscutfrom the material of the plate 19, forming a. resultant opening 23, atransversely `disposed inclined resilient tongue 24.

As assembled each unity 11 passes through the openings 18 in the endwalls of the units 10. A helical spring 26 in each unit has .one endpressing against its wall 17, and its other end abutting against theflange 22. In the adjacent unit the tongue 24 is rearwardly directed andin transverse align-y ment with the hole 27 near the end of the backwall 13. In order to free the adjacent unit it is merely necessary toforwardly press the tongue 24 into the plane of the openings 18 and theaction of the spring 26 will automatically withdraw the unit 11 with itsdepressed tongue from the adjacent unit. A convenient implement for thispurposeis a pin or otherl pointed tool 28 indicated in Figure 2 whereinthe broken lines show the depressed position of the tongue 24.

It will be observed that the removal of a unit by the describedoperation does not reduire anv slow and laborious4 tilting or twistingof either the unit to be removed or any remaining portion of the cha-in.Nor can the chain accidentally come apart by any twisting or turning ortilting motion.

I claim,

In a device ot' the type specilied, a series of hollow connected unitsprovided with openings in their ends, slidable connecting plates in theunits extending through the openings, anges upon the corresponding endsof the plates, compressible tongues upon the opposite ends of theplates, the units being provided with holes in substantial alignmentwith the tongues, and springs engaging the fianges and the adjacent endsof the units.

In testimony whereof I have affixed my signature. V

GEORGE KOLLSTEDE.
